Description

Technical Field

[0001] The present invention relates to a production tool, in particular to a bundling and shaping tool. Background Art

[0002] Wind turbine blades, as core components of wind turbines, are continuously becoming larger. Currently, large wind turbine blades all feature a skin-and-girder structure. The skin is primarily reinforced with fiberglass composite layers to provide aerodynamic shape and bear the majority of shear loads. The girder is now reinforced with a new unidirectional composite material layer made of fiberglass girders to support the blade shell structure. The web is a sandwich structure, providing support for the girder.

[0003] During the prefabrication process of the beam, the pultruded sheet is unrolled according to the dimensions on the drawing, and then cut and placed according to the pre-determined size. In order to maintain consistency with the beam profile of the shell blade mold, the beam should be fitted with the blade shell mold. When laying in an area where the curvature of the blade shell mold surface changes significantly, the sheet may not be easy to fit with the mold surface. In order to keep the sheet consistent with the surface of the blade shell mold during laying, the placed beam will be bundled with the shaping tool. However, the existing shaping tool can only correspond to one type of blade, and the shaping tool cannot be adjusted, which is limited by the bundling position, and blades of different shapes cannot be interchanged. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a bundling and shaping tooling, which effectively ensures the consistency of the laid beam and the blade shell mold surface, and can be adjusted to be suitable for the bundling of beams of different blade shapes, and has tooling interchangeability.

[0005] In order to solve the above technical problems, the present invention provides a bundling and shaping tool, which is characterized in that it includes a tool body and a shaping mechanism, and a plurality of the shaping mechanisms are movably provided on one side of the tool body, and the plurality of shaping mechanisms are parallel to each other and arranged at intervals, and the end of the shaping mechanism is provided with a supporting portion that can be supported on the workpiece surface. When the tool body is placed corresponding to the workpiece surface, the shaping mechanism can be moved and adjusted away from or close to the workpiece surface so that the supporting portion can be supported along with the workpiece surface, and the tool body is provided with a locking mechanism that can lock the moving position of the shaping mechanism.

[0006] Specifically, the tooling body includes a clamping plate 1 and a clamping plate 2 that are arranged opposite to each other, the shaping mechanism is arranged between the clamping plate 1 and the clamping plate 2, and the locking mechanism can drive the clamping plate 1 and the clamping plate 2 to approach each other to clamp the shaping mechanism.

[0007] Specifically, the shaping mechanism includes a slider, the abutting portion is connected to the slider, guide grooves are formed on the first and second clamping plates corresponding to the slider, and a sliding protrusion that can slide in the guide groove is formed on the slider.

[0008] Preferably, the abutting portion is rotatably connected to the slider.

[0009] More preferably, a rotation damper is provided between the abutting portion and the slider.

[0010] Specifically, the locking mechanism includes a fixing bolt and a fixing nut. The fixing bolt passes through the through holes on the first clamping plate and the second clamping plate and is threadedly connected to the fixing nut.

[0011] Specifically, the supporting portion is in the shape of an elongated strip.

[0012] Specifically, the supporting surface of the supporting portion supporting the workpiece profile is a plane or an arc surface.

[0013] Preferably, a protective film is provided on the abutting surface of the abutting portion abutting against the workpiece profile.

[0014] Specifically, the protective film is a PVC plastic protective film.

[0015] Through the above scheme, the beneficial effects of the present invention are as follows:

[0016] The bundling and shaping tooling of the present invention can be contacted with the corresponding position on the blade shell mold surface in advance, and the shaping mechanism can be moved away from or close to the blade shell mold surface so that the corresponding abutment of the shaping mechanism can abut on the corresponding blade shell mold surface. After confirming the adjustment position of each shaping mechanism, the moving position of the shaping mechanism is locked by the locking mechanism, so that the shape curve information of the blade mold surface can be recorded through multiple shaping mechanisms, and then it is tied and fixed with the sheet material to ensure that the laid beam can always be consistent with the blade shell mold surface. At the same time, because the shaping mechanism of the bundling and shaping tooling of the present invention can be moved and adjusted, it is not affected by the blade shape, has a highly free adjustment capability, is not restricted by the bundling position, and can be interchanged with the tooling.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, it cannot be understood as a limitation on the present invention. The directional terms of the present invention should be understood in conjunction with the actual installation status.

[0033] The present invention provides a binding and shaping tool, see Figure 1 As a specific embodiment of the bundling and shaping tooling of the present invention, it includes a tooling body 1 and a shaping mechanism 2. A plurality of shaping mechanisms 2 are movably provided on one side of the tooling body 1. The plurality of shaping mechanisms 2 are parallel to each other and arranged at intervals. The end of the shaping mechanism 2 is provided with a supporting portion 21 that can be supported on the workpiece surface. When the tooling body 1 is placed corresponding to the workpiece surface, the shaping mechanism 2 can be moved away from or close to the workpiece surface for adjustment, so that the supporting portion 21 can be supported along the workpiece surface. The tooling body 1 is provided with a locking mechanism 3 that can lock the moving position of the shaping mechanism 2.

[0034] When using sheet material to make a blade beam, the present invention's bundling and shaping tooling is first contacted with the corresponding position on the blade shell mold surface, and the side of the tooling body 1 provided with the shaping mechanism 2 is placed corresponding to the blade shell mold surface. The blade shell mold surface has a curvature change portion. By moving and adjusting the shaping mechanism 2, it can be moved away from or close to the blade shell mold surface, so that the corresponding abutment portion 21 of the shaping mechanism 2 can abut against the corresponding blade shell mold surface. After confirming the moving position of each shaping mechanism 2, the moving position of the shaping mechanism 2 is locked by the locking mechanism 3, so that multiple shaping mechanisms 2 can record the external curve information of the blade mold surface. After that, it is tied and fixed with the sheet material to ensure that the laid beam can be consistent with the blade shell mold surface. At the same time, because the shaping mechanism 2 of the bundling and shaping tooling of the present invention can be moved and adjusted, it will not be affected by the blade shape. The moving position of each shaping mechanism 2 can be adjusted according to the blade shape of the bundled blade, with a high degree of freedom of adjustment, not limited by the bundling position, and the tooling can be interchanged. It should be noted that the shaping mechanism 2 is made of a rigid material, and the bundling and shaping tooling of the present invention can be bundled and fixed using a flexible material tie band and sheet material.

[0035] See also Figure 1 and Figure 3 The tooling body 1 includes a clamping plate 11 and a clamping plate 2 12 that are arranged opposite to each other, and the forming mechanism 22 is arranged between the clamping plate 11 and the clamping plate 2 12. The locking mechanism 3 can drive the clamping plate 11 and the clamping plate 2 12 to approach each other to clamp the forming mechanism 2, thereby increasing the clamping force of the clamping plate 11 and the clamping plate 2 12 on the forming mechanism 2 and locking the moving position of the forming mechanism 2.

[0036] The shaping mechanism 2 includes a slider 22, the abutting portion 21 is connected to the slider 22, the clamping plate 11 and the clamping plate 2 12 clamp the slider 22, and a guide groove is formed on the clamping plate 11 and the clamping plate 2 12 at the position corresponding to the slider 22, see Figure 1 and Figure 3A guide groove 1101 is provided on the first clamping plate 11, and a guide groove 2102 is provided on the second clamping plate 12. A sliding protrusion 23 capable of sliding in the guide groove is formed on the slider 22. The length of the guide groove determines the adjustment range of the shaping mechanism 2. The length and position of the guide groove should be set according to actual conditions. It should be noted that one end of the slider 22 extends outward from one side of the tooling body 1, and the abutting portion 21 is connected to the protruding end of the slider 22, ensuring that the abutting portion 21 can always be on the outside of the tooling body 1, making it convenient for the abutting portion 21 to abut against the workpiece surface.

[0037] See also Figure 1 and Figure 3 The guide groove is preferably a rectangular groove. Figure 3 In the orientation shown, the length direction of the guide groove is up and down, that is, the moving direction of the slider 22 is up and down, the sliding protrusion 23 is a rectangular parallelepiped, and the opposite two sides of the sliding protrusion 23 are in contact with the two sides of the guide groove, so that the sliding protrusion 23 will not shake or deflect during the process of sliding up and down in the guide groove, thereby ensuring the stability of the shaping mechanism 2 during the bundling process.

[0038] As a preferred embodiment of the bundling and shaping tooling of the present invention, see Figure 1-3 The supporting portion 21 is rotatably connected to the slider 22. By adjusting the rotation angle of the supporting portion 21, the inclination angle of the supporting surface of the supporting portion 21 for supporting the workpiece profile can be freely adjusted to ensure that the supporting portion 21 can fully contact the sheet during the bundling process.

[0039] Furthermore, a rotation damper is provided between the abutting portion 21 and the slider 22, so that there is rotation damping between the abutting portion 21 and the slider 22, so that when the bundling shaping tool of the present invention is tied and fixed to the sheet material, the abutting portion 21 and the slider 22 will not rotate easily under the action of the damping, which can ensure that the sheet material does not slide or dislocate.

[0040] See also Figure 3The locking mechanism 3 includes a fixing bolt 31 and a fixing nut 32. The fixing bolt 31 passes through the through holes on the splint 11 and the splint 2 12 and is threadedly connected to the fixing nut 32. By tightening the fixing nut 32, the splint 11 and the splint 2 12 are driven to approach each other, thereby clamping the slider 22, increasing the friction between the slider 22 and the splint 11 and the splint 2 12, locking the slider 22, and preventing the slider 22 from sliding relative to the tooling body 1. It should be noted that when it is necessary to move and adjust the slider 22, the fixing nut 32 can be loosened appropriately so that the slider 22 can slide up and down just under the action of the guide groove, and at the same time, the slider 22 can fit just well with the splint 11 and the splint 22, so that the slider 22 will not shake between the splint 11 and the splint 22 while sliding, thereby ensuring the accuracy of the moving position of the shaping mechanism 2. In addition, multiple sets of fixing bolts 31 and fixing nuts 32 are provided on the tooling body 1, such as Figure 1 As shown, there are five groups of fixing bolts 31 and fixing nuts 32, which are divided into two layers, the upper layer is provided with three groups, and the lower side is provided with two groups, and the intervals are reasonably set according to the left and right widths of the tooling body 1 to ensure that when the five groups of fixing bolts 31 and fixing nuts 32 are tightened, the sliders 22 of all the forming mechanisms 2 can be clamped by the clamping plate 11 and the clamping plate 22 to form a locked state.

[0041] As a preferred embodiment of the bundling and shaping tooling of the present invention, see Figure 1-3 The supporting portion 21 is in the shape of a long strip, and its length direction is perpendicular to the arrangement direction of the shaping mechanism 2, which can increase the contact area between the supporting portion 21 and the sheet material, and further ensure the consistency of the beam and the blade shell mold surface.

[0042] The blade beam is formed by splicing multiple sheets in the horizontal direction and stacking in the vertical direction. In order to ensure the fit, the supporting surface of the supporting part 21 that is pressed against the workpiece surface is a plane, and the supporting part 21 is directly pressed against the sheet to form a surface contact through the plane; of course, the supporting part 21 can also be an arc surface, and the supporting part 21 is pressed against the sheet to form a line contact.

[0043] In addition, in order to prevent the binding and shaping tooling of the present invention from contaminating the surface of the beam when it comes into contact with the sheet material, thereby affecting the subsequent beam pouring quality, preferably, see Figure 2 and Figure 3 The abutting surface of the abutting portion 21 abutting against the workpiece profile is provided with a protective film 24. Further preferably, the protective film 24 is a PVC (polyvinyl chloride) plastic protective film.

[0044] In order to better understand the technical solution of the bundling and shaping tooling of the present invention, the following is an explanation in combination with relatively preferred technical features.

[0045] See also Figure 1-3The bundling and shaping tooling of the present invention includes a tooling limb 1 and a shaping mechanism 2. A plurality of shaping mechanisms 2 are movably arranged on one side of the tooling main body 1. The plurality of shaping mechanisms 2 are parallel to each other and arranged at intervals. The tooling main body 1 includes a clamping plate 11 and a clamping plate 2 12 that are relatively arranged. The shaping mechanism 2 includes a supporting portion 21 and a slider 22, wherein the slider 22 is arranged between the clamping plate 1 11 and the clamping plate 2 12, and a guide groove is formed at the clamping plate 1 11 and the clamping plate 2 12 corresponding to the slider 22. A sliding protrusion 23 that can slide in the guide groove is formed on the slider 22. The supporting portion 21 is arranged at one end of the tooling main body 1 extending outside the slider 22. The position of the supporting portion 21 is adjusted by moving the slider 22. When the tooling main body 1 is placed corresponding to the blade shell mold surface, the supporting portion 21 is moved away from or close to the mold surface for adjustment, so that the plurality of supporting portions 21 can be pressed against the blade shell mold surface according to the shape. The support portion 21 is rotatably connected to the slider 22, so that the support portion 21 can be rotated to adjust the inclination angle of the support surface, so that the support surface of the support portion 21 can be more fully fitted to the blade shell mold surface. After all the shaping mechanisms 2 are adjusted to their positions, the support portions of multiple shaping mechanisms 2 are all pressed against the blade mold surface, thereby realizing the recording of the shape curve information of the blade mold surface. By tightening the fixing nut 32, the clamping plate 11 and the clamping plate 2 12 are driven together by the fixing bolt 31 and the fixing nut 32 to approach each other, so as to strengthen the clamping force of the two on the slider 22 and realize the locking of the shaping mechanism 2. When laying the blade beam, the bundling and shaping tooling of the present invention is bundled and fixed with the sheet material, so that the support portion 21 is pressed against the blade and bundled and fixed, effectively ensuring the consistency of the laid beam and the blade shell mold surface. A rotation damper is provided between the abutting portion 21 and the slider 22, so that the rotation between the two is damped, thereby preventing the sheet from sliding and misaligning during the bundling and fixing process. A PVC plastic protective film is also provided on the abutting surface of the abutting portion 21 to prevent contamination caused by contact between the abutting portion 21 and the sheet, thereby affecting the quality of subsequent beam pouring. The bundling and shaping tooling of the present invention can effectively ensure the consistency of the laid beam and the mold surface. At the same time, since the built-in slider 22 is a movable slider, it can be adjusted according to the blade shape and is suitable for bundling beams of multiple blade shapes. It has a highly free adjustment capability, is not restricted by the bundling position, and can be interchanged with the tooling.

[0046] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0048] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
